SEA SURFACE TEMPERATURE RESPONSE TO TYPHOON MORAKOT (2009) AND THE INFLUENCE ON ITS ACTIVITY
以2009年台风“莫拉克”为例,利用AVHRR/AMSR卫星数据和WRF模式,分析台风登陆过程中台湾岛周围海域SST变化特点及其对台风的影响.结果表明,由于海岸线的阻挡以及台风之前存在的冷涡的影响,“莫拉克”引起近海海域的最大降温位置出现在路径附近偏左或者离台风中心较远的海域.宽阔洋面上,台风活动导致的SST变化虽然减弱了台风强度,但对路径的影响小.沿海的SST梯度加强了台风的非对称结构,使得台风向非绝热加热大值区(台风北部)偏移.考虑近海SST…查看全部>>
While previous studies indicate that typhoons can decrease sea surface temperature (SST) along their tracks,a few studies suggest that the cooling patterns in coastal areas are different from those in the open sea.However,little is known about the ways induced cooling,coupled with the complex ocean circulation in the coastal areas,affects the track and intensity of tropical cyclones.The sea surface temperature responses to the landfalling process of Typhoon …查看全部>>
